Application ,filed My 'invention' relates to railway i rolling stock and consists in an*l improved truck rlhe object otmy invention is to provide a truck pedestal structure which is'j adapted to utilize either sta-ndardfrl. R. A.journal boxes or the anti-friction journal boxes which areV being used to Vsomeextent and which are substantially wider j@ lt. A.' boxes. i My invention A'enables the railroad com-V pany to change readily from one 'type of boxto the other without applyingT new pedestais. This makes arsubstantial saving in is material and labor it a change is to be made. `'there-the truck structure is ofthe type in which 'the pedestals are intJegral with the wheel pieces or with the entire truck frame, the cost of the change in boxes will be' only 2e a small traction of what it would be it' new Y perestals anclwheel pieces' or frame were required. ln my copending applicatiom Serial N um-l ber,l7ll,271, tiled March 10, 1 927, l describe 25,. and lclaim apedestal structure having the fsanie generalobject in. view, butin which Y .the change from a pedestal' taking an A. R.

A. box 'to a pedestal taking the larger antifrictionv box is' made by 'machining away a the pedestal legs. ln my present l invention, suoli` machining operations are eliminated RYA; boxpedestal A.` R. A. box pedestal to an anti-.rictionibox pedestal. which 'is not trucej of the structure of my copending application referred to.

yFigure 6 is a section through a pedestal leg and illustrates a modified form of the illerb'locl':` and pedestal.

rllhe truck shown in' Figure l includes the usual wheels 1, the axle journals 2 of .which mounttlie journal boxes 3 and 4. The journal v boxes" carry ordinary equalizers which support the truck frame wheel pieces 6 through springs 7 in the usual manner. rlhe Vtruck iframe illustrated is of the one-piece 'casting type' in which the pedestals are formed integrally with the Wheel. pieces, but obviously my invention is not limited' to this type of truck frame havvThe legs 8 .of each pedestal are spaced far enough` Yfrom each other to accommodate between'themthe wide anti-friction box 4v in'. substantially' the same manner as such .boxes are accommodated in ordinary pedestalsnow provided therefor. Each pedestal leg8,however, is adapted to mount a filler block 9 which then practially forms a part of the pedestal leg. The blocks on adjacent pedestal legs reduce the distance between thev journal box yengaging lfaces to such an extent Ythat the ordinary R. A. journal box may be assembled with the pedestal in proper operative relation. Preferably, the blocks 9 are partly chan# nelshaped' in` cross section and partly of hollow rectangular cross section and may be riveted or bolted to the pedestal leg. The sides of the blocks have lips 1l and the pedestal legs 8 are recessed adjacent the transverse WebsA as indicated at 10 to receive the lips' 11 Iof the blocks 9. Such an arrangement enables me to use the saine Wear plates l2 on the pedestal' legs in either adap- These wear plates may be spot-welded to the pedestal leg as indicatedmaaW'in Figure l or may be secured thereto by bolts 13 as detailed in. Figures 2 and 3.

, Gbviously'it is a comparatively simple ."inatter to eitherapply the filler blocks 9 or remove the blocks from 'the leg. Hence, the journal boxes may be changed from the A. R. A. type to the anti-frictiontype, or vice versa, at a minimum expense and Without replacing any of the other` truck parts.

The pedestal structure shown in Figure 4 resembles the ordinary pedestal in being adapted to be secured through its flange M to the pedestal leg of the cooperating leg.

to the wheel piece of a truck frame, but corresponds to the pedestals shown in Figures l, 2 andj3 in having its legs l5 adapted to mount filler blocks 16 and. to have a wear plate 17 secured to it over Athe liller block or over the face 18 ot the leg proper. i

rlChe leg structure illustrated in Figure 5 is substantially one-hall ot the complete pedestal shown in Figure Il and is adapted to be mounted on the wheel piece imlepemlently lt also includes a flange 19 for attaching the saine to the truck trame and a channel-shaped leg 20 adapted to mount the correspondingly shaped liller block 2l and, it desired, the Wear plate 22.

lFigure illustrates av variation in the pedestal and block assembly. ln this constructionthe block 23 has a central lip 24 and the pedestalv leg has a corresponding recess for this lip. lhese elements accurately position the block on the pedestal leg` and resist the thrusts otthe box due to the back and-forth play of the axle and wheel. The Wear late 25 is shown as welded to the pedestal lg. 'i

lt is apparent that the details ot the application of the filler blocks to the pedestal legs may be' otherwise modified, and other variations in the pedestal 'structure may be made Without departing tromthe spirit of my invention, and ll contemplate the exclusive use of all the features of my invention as are included in the scope of my claims.

ll claim: 1. A car truck pedestal leg having side walls and a transverse web between said side Walls, said'side Walls being provided with spaced bolt holes for securing a Wear plate in diii'erent positions relative to said web.

2. In combination, a car truck pedestal leg, having a lsmooth face adapted to guide a vertically movable journal box mounted in the pedestal, and a block detaehably seeuredto the inner face ot said' leg and havinga smooth tace adapted to similarly guide a narrower journal box mounted in the pedestal. y

3. ln combination, a car truck pedestal leg comprising side walls, a transverse web between said walls, a filler block in front of said web and detaehably secured to lsaid Walls, and a wear plate extending over said block and also secured to said Walls.v
